CAUTION As an antistatic precaution, do not touch exposed connector contacts!
Information about installing, performing an operational check, and verifying
the main antenna measurement system is explained in the appropriate
documentation listed below:
•
Agilent 85301B Antenna Measurement System Manual
•
Agilent 85301C Antenna Measurement System Manual
•
Agilent 85310A Distributed Frequency Converter Manual
If you purchased an Agilent 8511 as a stand-alone unit, refer to the Agilent
8530A On-Site Service Manual for installation instructions. Verify the 8511
as explained in its operating and service manual.
Installing the Agilent 85330A Multiple Channel
Controller
Choosing the Proper
Configuration There are two ways to install the Agilent 85330A system. Figure 1-1 on
page 1-3 is a flow chart that shows a installation configuration that is
appropriate for you to use.
How to use the figure
Follow the flow chart from the top. Determine if your measurements are
made with a single frequency (CW), or multiple frequencies. Proceed down
the appropriate flow chart path. Proceed in this way until you get to a box
that recommends either
Figure 1-2 on page 1-4 , or Figure 1-3 on page 1-5 .
Fast Source Control
Fast source control speeds up frequency switching speed in
multiple-frequency measurements. It is only available in systems that use
two Agilent 836xx series synthesized sources. This mode uses TTL signals
to increment RF and LO source frequency, providing faster frequency
switching speeds than are possible under 8530A control. In the fast source
control configuration, the system’s computer must set up the sources with
appropriate frequency settings, triggering mode, and so on. When automatic
Run Time measurement mode is engaged, the 85330A automatically
increments the RF and LO source frequencies using TTL lines. More
information is provided in
Chapter 6, “Programming.” When the sources are
controlled by a computer, the SCPI language mode must be selected. This is
shown in
Figure 1-3 on page 1-5 .
